Bitcoin spot ETFs recorded $999 million in net inflows on September 21.
BlackRock’s IBIT led Bitcoin funds with $381 million in inflows.
Ether spot ETFs added $270 million, including $110 million into BlackRock’s ETHA.

U.S. spot Bitcoin ETFs recorded $999 million in net inflows on September 21, according to data from SoSoValue. The daily total came close to the $1 billion mark, showing strong demand for Bitcoin exposure through exchange-traded funds during the session.

BlackRock’s iShares Bitcoin Trust (IBIT) led the category with $381 million in net inflows. That accounted for roughly 38% of the total reported for U.S. spot Bitcoin ETFs.

ETF inflows indicate that more capital entered the funds than left them over the trading day. While the figures offer a useful view of investor demand, they do not guarantee that Bitcoin’s price will rise.

BlackRock Leads as Ether ETFs Attract $270M

Bitcoin was not the only cryptocurrency to see positive ETF flows on September 21. U.S. spot Ether ETFs attracted another $270 million in net inflows.

BlackRock’s iShares Ethereum Trust (ETHA) recorded $110 million, representing approximately 41% of the Ether ETF category’s daily total.

Together, Bitcoin and Ether spot ETFs brought in about $1.27 billion in net inflows for the session. The positive figures across both categories suggest that demand was not limited to a single crypto asset or fund.

The results also show the scale of BlackRock’s contribution: IBIT and ETHA accounted for a combined $491 million in net inflows.

What the Latest Bitcoin ETF Inflows Mean

The September 21 figures put Bitcoin ETF inflows back in focus after a period of mixed daily results across crypto investment products.

For investors, sustained inflows can signal continued interest in gaining cryptocurrency exposure through regulated funds. However, daily flows can change quickly, and a strong session does not establish a lasting trend on its own.

The next trading days will show whether demand remains positive for both Bitcoin and Ether ETFs or whether the latest inflows prove temporary.
